Having spent hours reading about heaters, air con and all the issues, I decided today to have a look under the dash to see for myself what a complete nightmare of a job it could be. A friend did a scan for me last week and there were several codes, but nothing to sweat about, In saying this there’s nothing to sweat about in the car either as the heater i crap.
The symptoms are this: it doesn’t blow hot, it doesn’t blow cold, it blows very little, the fan sounds like it’s moving a lot of air??
The scan showed heater flap issues, high pressure switch and the infamous G263 sensor. I have ordered the parts and waiting for them to arrive. I started on the drivers side, following what I’ve read on here….trims out, ally plate out, flap motor out, look up and see the G263 senso, manage to pull it out, have a look and put it all back together. I Will say it’s not the easiest job in the world, it I’ve done far worse (see my other alternator post today). I tried up, vents and down and watched the lever move, and all seems well?
i then moved over to the passenger side…glove box out, vent removed, look for the motor levers, cycle the hot and cold flap, and the screen flap both appear to work fine? At this point I remember reading about the pollen filter, maybe it’s blocked? I lay underneath trying to figure out how to remove it and soon spot the problem…..and this is weird!…. The long ‘L’ shape retainer was on back to front leaving a gaping hole at the front, and the filter was in the wrong way round and full of crap, so basically 90% of the air was escaping before it gets anywhere near the action!! As a test I removed the filter and put the plate back the correct way around….and hey presto! A short drive later and the heater is super, so that’s now another bit on order.
Its obviously been like this for some time, surely a previous owner must have noticed the lack of ventilation after a service?? Odd.
Its now a wait for parts to arrive, and hopefully I’ll have the air conditioning working too, I’ll keep you posted.
